Unexpected escape characters in the device's prompt

NSO -> NCS6K IOS-XR 6.2.3

Normally we expect the prompt 'sysadmin-vm:0_RP0#'

On one device, when in admin mode, we are getting: [?7hsysadmin-vm:0_RP0# *** IDLE TIMEOUT ***

Which we don''t match, and hence the timeout. 

This looks like an ANSI Escape sequence ([?7h - wraparound on). So what should we be doing? Get NSO to interpret / cope with escape sequences, or can we stop the device sending them?

 

Help!
